Second hand shops sell more and more "new" clothes so finding an authentic vintage look is not always so easy. Men's Health released a tutorial on how to treat your new t-shirt with some basic household supplies to get the worn look. In addition to the soda treatment and sanding the print, also the neckline and sleeve openings have to be treated lightly with sandpaper. Neck opening should be stretched a bit when it comes off wash. For these treatments use more patience than force. A good vintage treatment takes time. If you want to change the color to a more older looking yellowish tone, let the shirt soak in a bucket full of strong espresso coffee for a day or two.
